Title: Optical disk revolving mechanism
Inventor: OSUMI AKITAKE
IPC: G11B17/028
Filed: 1988-04-08
Abstract: PURPOSE:To prevent the set dislocation of an optical disk at the time of using high temperature by providing a shaft center hole on the rotary shaft of a motor, integrating a shaft to have a semi-sphere-shaped leading part which is movable in a shaft direction and engaging the semi-sphere-shaped leading part with the center hole of the optical disk. CONSTITUTION:Just before an optical disk 5 is placed on a turn table 4, a center hole 5b of the optical disk 5 and a semi-sphere-shaped head part 3a of a shaft 3 are brought into contacted with each other and engaged and the centering of the optical disk 5 is executed. Next, when the optical disk 5 is pressed down by the pressing-down force of a clamp 6, simultaneously, the semi-sphere-shaped leading part 3a is also lowered and the optical disk 5 is pressurized contact to the turn table 4. Thus, by engaging the semi-sphere-shaped leading part 3a and the center hole 5b of the optical disk 5, the set dislocation can be prevented from being generated at high temperature, when a room temperature and a temperature in a device are increased.

Abstract: PURPOSE:To stably form an anodically oxidized film without Al being melted when Al2O3 as an insulating layer is formed on a gate electrode and wiring by Al of a thin film transistor by anodic oxidation by controlling current for anodic oxidation to the necessary minimum. CONSTITUTION:An Al film is formed on the surface of a substrate 1 such as glass to form a gate electrode and gate wiring 2. Next, a mounting part of the gate wiring is coated with a resist to prevent anodic oxidation and is energized in electrolytic solution consisting of ethylene glycol and water at a volume ratio of 7:3-9:1 with the gate electrode and the gate wiring by Al being made an anode to subject a part that is not coated with the resist to anodic oxidation and to form an insulating layer 3 by Al2O3. A current flowing in Al2 on the anodic oxidation is normally detected and the value is controlled to the necessary minimum, allowing the electrolytic solution to infiltrate into the interface between the Al and the resist in the boundary part between the mounting part of the gate wiring 2 and the resist. Thus, an anodically oxidized film 3 is stably formed without trouble which the Al2 is melted.

Abstract: PROBLEM TO BE SOLVED: To prevent a collapse of minute space by a method wherein a collapse rate of the minute space formed in an inner layer is made at most a specific value. SOLUTION: A collapse rate of discharge space is detected according to the following formula. R(%)=(A-B)/A×100 Where A is a gap of an edge part of the discharge space, and B is a gap of a central part of the discharge space. In this example, the collapse rate of the discharge space is 5-15%, i.e., at most 20% and preferable.

By integrating the green sheets 21, 22 and 23 by laminating, an inner wall of the hole part 31 can be prevented from being deformed. Then, by extracting a shape holding material 40 from the green sheet laminated material, minute space which is free from any collapse can be formed in the inner layer of the green sheet laminated material.  Thereafter, by burning the green sheet laminated material, an alumina-made ozonizer cell having discharge space of at most 20% collapse rate can be obtained.
